This data repository contains reconstructed and quantitatively analyzed gas-liquid two-phase distributions obtained from a centrifugal pump mock-up whose geometry is related to a commercially available industrial centrifugal pump. As measurement system the ultrafast electron beam X-ray CT scanner (UFXCT) is applied with a frame rate of 2,500 Hz, single-plane mode and a total scanning interval of 5 seconds. The data repository contains:

Reconstructed raw data sets (Algebraic Reconstruction Technique from the UFO framework) for different inlet gas fractions (eps0.0xx) at constant 1480 rpm and for both rotating and back-rotated impeller positions, respectively
Extracted RPM per CT scan (frame) including its raw data
Extracted angular positions of the impeller mock-up per frame
Calculated quantitative gas fraction data sets (static impeller position)
Time-averaged gas fraction distribution and its corresponding averaged variance
Pump and impeller mask data
Additional data obtained from the SPS server with a sampling frequency of 1 Hz

Data is stored in HDF5 format.
